Where Autumn Pollen Comes From

Unlike spring, when tree pollen is the main cause, the pollen that commonly causes allergies in autumn mostly comes from weeds. These plants are found widely in fields, along riverbanks, on waste ground, and in city green spaces. When the weather is clear, windy, and the air is dry, pollen can stay floating in the air for longer.

What the Symptoms Are Like

Typical symptoms include an itchy nose, repeated sneezing, clear runny nose, and itchy eyes, watery eyes, and an itchy throat. Some people mainly have eye symptoms, and their eyelids may even swell. Symptoms that appear at a similar time every year are an important clue.

What You Can Do

  • Follow local autumn pollen monitoring information and spend less time outdoors during peak times
  • Wear a mask and goggles when you go out, and change your clothes, wash your face, and rinse your nose after getting home
  • Dry clothes indoors instead of outdoors to reduce pollen coming into the home on your clothes
  • If symptoms are obvious, see a doctor for an assessment so they can make a proper plan

Autumn allergies often happen along with other breathing problems. If you also have repeated wheezing, chest tightness, or a cough that does not go away, it is best to see a doctor early for an assessment. Do not treat it yourself as "pharyngitis" for a long time.
